Description

Drainage structure for purification {DRAINAGE FOR ROAD}

The present invention relates to the field of environmental civil engineering, and more particularly, to a purification drainage structure for purifying and draining rainwater that has washed off a non-point pollutant on a road surface.

Sources of pollutants are classified into point sources and nonpoint sources based on whether their outlets are specified in a specific location.

Non-point source is a case where the pollutant is discharged through the discharge port of a specific place, such as sewage treatment plant, wastewater treatment plant of industrial plant, livestock, manure, leachate and the like.

Non-point source is a case where the discharge port of pollutants cannot be specified, such as pollutants accumulated on the top of roads and bridges, fine dust such as vehicle exhaust gas and tires, and pollutants accumulated on the surface of construction sites such as road farmland For example, these pollutants are a representative cause of water pollution because it is introduced into the stream with rainwater (rain water) during rainy weather.

Since most of these non-point sources are washed by rainfall within a certain time from the start of the rainfall, that is, the initial storm, it is important to purify the initial storm, and then the purification of the continuous storm is not meaningful.

Therefore, if the purification to lasting rain has little effect on the purifying power, unnecessarily large capacity of the purification capacity, only the volume and cost burden has a big problem.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a drainage structure for purification in which the initial stormwater is efficiently purified and the continuous stormwater is immediately discharged.

Still another object of the present invention is to provide a more effective purification drainage structure, particularly when installed on adjacent slopes 6 of hilly or mountain cut roads.

In order to solve the above problems, the present invention is provided with a partition wall (10A) so that the flow of water drained on one side overflows, drainage, the opening 10B to bypass the drained water upstream than the partition (10A) A formed drain 10; Purification drainage, characterized in that; to handle the contamination of the depleted flowing water through the opening (10B) of the drainage path 10, and to guide the contaminated treated water to the drainage path (10); Present the structure (2).

The purification drainage structure (2) is installed for drainage of roads (4) cut through hills or mountains; The drainage passage 10 is formed on at least one of both sides of the roadway 4 along the roadway 4 and a first drainage path 12 below the adjacent slope 4 of the roadway 4. The second drainage passage 16 spaced apart from the first drainage passage 12, and installed on an adjacent slope surface 6 of the road 4, connects the first drainage passage 12 and the second drainage passage 16 and the partition wall. It may include; (10A) is provided with a connection drainage channel 14 formed with the opening (10B).

The partition 10A may be formed at a height lower than the depth of the drainage path 10.

The opening 10B of the drainage passage 10 may be formed at a position lower than the partition 10A along the depth of the drainage passage 10.

The partition 10A is perpendicular to the connection drain 14; The opening 10B of the drainage passage 10 is formed on one side of both sidewalls of the connection drainage passage 14, and the partition 10A is an opening 10B of the drainage passage 10 with respect to the connection drainage passage 14. ) May be inclined toward the second drainage channel 16 from the first drainage channel 12 toward one side thereof.

The pollution treatment unit 20 may be installed at a lower side of the adjacent slope 4 of the road 4. In this case, the pollution treatment unit 20 may be connected to the second drain 16, the drain 20B for draining the polluted water flow.

At least a lower portion of the pollution treatment unit 20 may be buried in the adjacent slope 6 of the road 4.

In the pollution treatment unit 20, an inlet 20A through which the depleted water flowing through the opening 10B of the drainage path 10 flows may be located at an upper side, and a drain hole 20B may be located at the lower side.

The pollution treatment unit 20 may include a hole hole 22 to drain the treated running water to the drainage passage 10.

The present invention can purify efficiently because the initial rainwater can be immediately discharged and the sustained rainwater can be discharged immediately, and the purification capacity can be reduced.

In addition, the present invention can be separated from the initial rainwater and the sustained rainwater according to the water level (C) simply structurally by the partition wall.

In addition, the present invention can be installed using the existing drainage.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown below in Figure 1, the purification drainage structure 2 according to the present invention is installed for the drainage of the road 4, in order to clean the initial rainwater, in particular to wash off the non-point source of pollution on the road (4) surface The partition wall 10A is provided to drain and flow the drained water on one side, and the drained water can be bypassed upstream of the partition wall 10A (that is, upstream in the flow direction drained along the drainage path 10). The pollution treatment unit 20 for treating the non-point source of the depleted water flowing through the drain 10 having the opening 10B and the drain 10 having the opening 10B, and guiding the polluted processed water to the drain 10. It may include.

That is, since the rainfall amount in the initial stage of rainfall is not a lot of rainwater in the drain 14, the water level (C) of the running water in the drain 10 is low, and as shown by the arrow A according to the flow of water in the drain 10 is partition 10A ) Is bypassed to the pollution treatment unit 20 through the opening (10B) of the drainage path (10). That is, the initial rainwater may be drained to the drainage path 10 after being purified by the pollution treatment unit 20.

As the rainfall continues, the amount of rainwater in the drainage passage 10 increases, so that the water level C in the drainage passage 10 becomes higher than the partition 10A. Overflow 10A can be drained directly to the drainage path 10. That is, the sustained rainwater can be bypassed to the pollution treatment unit 20 through the opening 10B of some drainage passage 10, but it can be seen that a considerable amount is discharged directly into the drainage passage 10 without bypassing the pollution treatment portion 20. .

Accordingly, since the initial rainwater can be purified by the purification drainage structure 2 according to the present invention and the sustained rainwater can be discharged immediately, the pollution treatment unit 20 can be manufactured in a small capacity corresponding to the initial rainwater amount, and also the boiling point. It can create the effect that the pollutant can be sufficiently purified.

In addition, the purification drainage structure 2 according to the present invention can be separated by the partition 10A structurally and simply separate the initial rainwater and the continuous rainwater according to the water level (C) in the drainage path 10 according to the rainfall duration, rainfall. .

In addition, the purification drainage structure 2 according to the present invention further installs the partition 10A in the existing drainage passage 10 and drills through the opening 10B, the existing drainage passage 10 and the pollution treatment unit 20 are simply installed. The bar can be connected to the existing installed drainage system (2).

Meanwhile, the purification drainage structure 2 according to the present invention may more preferably have the following characteristics.

That is, the partition wall (10A) is formed to a predetermined height for the separation of the initial rainwater and the continuous rainwater, but is formed at a height lower than the depth of the drainage passage 10, so that the continuous rainwater overflows the drainage passage (10) around the connection drainage path (14) It may be more desirable to prevent flooding.

In addition, the partition wall 10A may be vertically formed with respect to the drainage path 10, that is, with respect to the flow direction of the drainage along the drainage path 10, as shown in FIGS. 1 and 2.

Alternatively, as shown in FIG. 5, when the opening 10B of the drainage passage 10 is formed at one side of both sidewalls of the drainage passage 10, more precisely, the connection drainage passage 14, the partition 10A may have an initial rainwater. It may be formed to be inclined with respect to the drainage passage 10, that is, the connection drainage passage 14 so as to more effectively flow into the opening 10B of the drainage passage 10. That is, the partition wall 10A may be formed to be inclined toward the second drain passage 16 from the first drain passage 12 toward one side where the opening 10B of the drain passage 10 is formed. In this case, the running water in the drainage passage 10 can be guided more effectively to the opening 10B of the drainage passage 10 by the partition 10A.

In addition, the opening 10B of the drainage passage 10 may easily bypass the flow-through part 20 through the opening 10B of the drainage passage 10 that is not flown by the partition 10A in the drainage passage 10. In order to achieve this, it may be formed at a position lower than the partition wall 10A along the depth of the drainage passage 10. More preferably, it may be more preferable that the opening 10B of the drainage passage 10 is formed near the bottom of the drainage passage 10.

In addition, the pollution treatment unit 20 may be composed of any medium as long as it can clean the non-point pollutant, and more preferably, it may be composed of an environment-friendly medium using sand, gravel, crushed stone, filler, and the like.

In addition, the pollution treatment unit 20 may be installed in the drain hole (20B) in which the discharged water purified by the pollution treatment unit 20 is drained, a hole hole 22 formed with small holes for more effective drainage of the purified water. .

As described above, the purification drainage structure 2 according to the present invention inclines hilly areas or mountains so that the initial rainwater can easily be easily penetrated into the pollution treatment unit 20 by gravity and then drained back to the drainage path 10. It may be implemented for the drainage of one road 4. That is, the drainage structure 2 for purification according to the present invention may be installed on an adjacent slope 6 of a hill 4 or a road cut through a mountain.

In this case, in particular, the drainage passage 10 is a first drainage passage 12 provided along at least one of both sides of the roadway 4 along the roadway 4 and a first drainage path below the adjacent sloped surface 6 of the roadway 4. The second drainage passage 16 is spaced apart from the 12 and connected to the sump well, and is installed on the adjacent slope surface 6 of the road 4 to connect the first drainage passage 12 and the second drainage passage 16 and the partition wall. It may be configured to include a connection drainage path 14 provided with a 10A and an opening 10B.

In addition, the flow rate of the flowing water in the connecting drain 14 becomes faster toward the second drain 16, so that the flowing water in the connecting drain 14 may be easily and effectively penetrated into the pollution treating unit 20 (contamination treatment unit ( 20 may be more preferably installed below the adjacent slopes 6 of the roadway 4. In this case, it may be more preferable that the pollution treatment unit 20 drains the purified water to the second drain passage 16. That is, the pollution treatment unit 20 may be connected to the second drain 16, the drain 20B for draining the purified water flow. In addition, the second drain 16 may have a treatment water inlet 10C connected to the drain 20B of the pollution treatment unit 20.

In addition, since the pollution treatment unit 20 is more preferably concealed to prevent damage to the surrounding landscape, at least a lower portion thereof may be embedded in the adjacent slope surface 6 of the roadway 4.

In addition, the pollution treatment unit 20 is an inlet 20A through which the depleted water flows in through the opening 10B of the connection drainage path 14 so that the flowing water can be quickly treated by gravity and then drained to the second drainage path 16. ) May be located at the upper side, and the drain 20B may be located at the lower side of the pollution treatment unit 20.

Since the above has been described only with respect to some of the preferred embodiments that can be implemented by the present invention, the scope of the present invention, as is well known, should not be construed as limited to the above embodiments, the present invention described above It will be said that both the technical idea and the technical idea which together with the base are included in the scope of the present invention.
